This invention relates to an improvement in barricades or bulkheads, for freight car loadings, of the type shown in my application Serial No. 670,178, filed May 16,, 19%, now abandoned.

One of the objects of my invention is to provide a bulkhead or barricade of the type shown in the above-entitled application, in which not only the cross strips or straps between'the frame members are formed of metal, but all parts of the bulkhead are formed of metal.

Another object of my invention is the provision of improved means for anchoring the bulkhead by wedging or jamming between the sides of a car or carrier, all, or substantially all, of such anchoring means being carried by the bulkhead.

A still further object of my invention is to p ov de a bulkhead or barrier w en positioned again t a l ad in a carrier and we ed bet ee the walls thereof. Shocks or the load a ainst the barrier will increase the jamming of the barricade between sides of the carrier.

Having now described, in a general way, the nature and purpose of this invention, I will proceed for illustrative purposes, to a detailed description of a preferred embodiment thereof, with reference to the accompanying drawings in which:

Fig. 1 is a face view of one form of bulkhead in accordance with my invention;

Fig. 1A is a plan view thereof;

Fig. 2 is a perspective view of one of the screw jacks for securing the bulkhead shown in Fig. l in position in a car;

Fig. 3 is a perspective view of a modified form of barricade positioned, as positioned in a car, portions of a car being shown in dot and dash lines;

Fig. 4 is a detail face view of the right hand end of the upper rail with a portion in section;

Fig. 5 is a sectional view of the line 5-5 of Fig. 4 on a larger scale; i

Fig. 6 is a sectional view on the line 6-6 of Fig. 3;

Fig. 7 is a perspective view of the lower end of; a side frame member with a securing foot welded thereto; J

Fig. 8 is a face view of a modified form similar to Fig. l;

Fig. 8A is a top plan view of the structure shown in Figure 8; and

Fig. 9 is a face view of one of the lower corners of the structure shown in Fig. 8 with portions in section.

Referring to the form shown in Fig. 1 of the drawings. the bulkhead comprises a frame formed o upper and l we horizontal rails A. nd vertica supports B. B, to wh ch the ends of the rails are welded The rails A, A. a d the ve t col 8 nports B. 3. are for. .d of channel sections. w th t eir flanges ext ndi owerds each other with. t e webs on. the outer fac thereof- Welded to a rail member- A and vertical support at each corner of the frame is an angular strut or brace C, which not only reinforce the frame. against corner stresses, but reinforce the intermediate portions of the rails A, A and supports B, B, against bending stresses caused during the application of straps extending from member to member during the tensioning thereof when securing them to the members A, A and B, B as hereinafter described.

Welded to each vertical support 13 is a handle D, and b is a skid plate welded to the bottom thereof thus providing easy handling means as the car loaders can grasp the handles and slide the structure on the skid plates.

The rails are preferably cambered as shown in Fig. 1A to provide convex faces adapted to be engaged by the freight when the bulkhead is positioned in a car against the freight to be held thereby. I

Welded to one flange of each rail A and one flange of each support B on the freight engaging side of the bulkhead are spaced eyes Ill. Transverse metal strips or straps I2 are connected to the opposite eyes on the supports B, the ends thereof being secured to the body of the strip by clips l4, and 16 are similar strips connecting opposite eyes It extending from the rails A, A which are interwoven with the strips l2.

Mounted at each junction of a rail .A and a support B is a screw jack having a nut I8, preferably secured to the flange of the rail, opposite the flange to which the eyes Ill are attached. Threaded in the nut of each jack is a screw l9 having a shoulder 20 provided with openings through which a headed actuating lever 21 freely extends, and is also provided with a head 22 at the end of a neck extending from the shoulder in axial alignment with the screw [9. The head 22 is rotatably mounted in a tubular member 28 extending from a plate 23* provided with spurs extending from the outer face of the plate for the purpose hereinafter described. The end of the tubular member 23 is provided with an annular flange between the head 22 and shoulder 20 and forms an abutment against which the head bears when the bulkhead is positioned in a car as well as retains the plate 23 on the head.

If desired, a plate such as 23 may be secured to one support B in the plane of a rail A. and both the upper portion and lower portion of the frame secured in position by jacks at the other side of the frame.

When positioning a bulkhead in a freight car after the same has been loaded, the bulkhead is positioned in front of the load with the bowed side of the rails A, A in contact with the load. The bulkhead is then forced against the load and the jacks are manipulated to embed the spurs into the Walls of; the car and press the pla es 4 agains he Walls. ther y firm y i mming the bulkhead between the walls of the car.

After the jacks have secured the bulkhead in position, the actuating levers 2! will drop by gravity as shown in Fig. 1, the weight of the levers will prevent the screws 19 from being turned by vibration and thus tending to turn the screws of the jacks.

In the structure shown in Figs. 3-7 of the drawings the frame of the bulkhead is also formed of upper and lower rails A, A and supports B, B, all formed of channel sections, the flanges of the supports being spread to form seats for the reception of the rails A, A, the outer faces of the webs of the rails A, A are seated against the inner faces of the webs of the supports B, B. After the frame members are positioned relative to each, the flanges of the supports B, B are welded to the flanges and webs of the rails A, A whereby a rigid frame structure is provided.

Before the frame members are secured to each other, the rails A, A are also cambered as shown in Fig. 1A so as to curve the outer faces of the webs of the rails A, A to bow them outwardly to provide convex faces to be positioned against the load to be secured by the bulkhead. The frame is also provided with four corner braces C, formed of angle sections, the ends of which are welded to the flanges of the rails A, A and supports B, B so positioned that a broad face of one of the flanges of each brace is substantially in the plane of the faces of the webs of the rails A, A and supports B, B, thus broad faces of all of the frame members face the freight to be retained by the bulkhead.

Welded to the outer face of each of the inner flanges of the rails A, A and the supports B, B

.are spaced eyes H], which are substantially in the plane of the webs of the channel sections forming the frame.

After the frame members are secured to each other, transverse straps 12 are connected to the eyes In on the side supports 13, B. The vertical strips I6 are passed through eyes I0 on rails A, A. and are interwoven with the transverse strips [6 as in Fig. 1.

In order to retain the lower ends of the sup;- ports B, B against the freight, I may provide a chock formed of a wooden block 24 adapted to be spiked to the floor of the car, and secured to the lower end of each support A is a skid plate 26 having an opening positioned to match one of the spike openings in the chock 24, or the plate may be nailed directly to the floor of the car.

In order to secure the upper end of the bulkmeans comprises a wall plate 28, provided on itsrear face with a plurality of spurs, which are driven into the side of the car and the plate is then fixedly secured by lag screws extending through openings in the plate. Pivotally secured to the front face of the plate 23 by means of an eye 30, is a hook 32, which is engaged by one of the links of a chain 34 connected to the upper portion of a support B to hold the bulkhead against movement by the freight.

The other securing means may also be considered as a wedge actuated jack which comprises a bolt 36, slidably mounted within the recess formed between the web and flanges of th upper frame rail A, and is retained therein by means of a plate 38 welded to the flanges of the rail. The bolt is formed of a channel section, the

flanges slidably engaging the flanges of the rail A. The forward end of the bolt has a plate it welded thereto and is provided with spurs which are driven into the wall of the car. The rear end of the bolt is adapted to be engaged by a wedge 42 seated in slots in the flanges of the upper rail member A. The wedge is provided with a plurality of openings 43 for the reception of a pin 44 for securing the wedge in its adjusted position. Both the wedge 42 and pin 44 may be connected to the bulkhead by means of a chain (not shown) to prevent loss, when the bulkhead is not in use. The web of the channel section forming the bolt is provided with a slot 46, and 48 is a screw extending through the plate 38, the slot 46 and is threaded into the web of the rail A. This arrangement permits sufficient movement of the bolt for securing the bulkhead in the car and freeing the bolt from the car when removing the bulkhead while preventing the removal of the bolt from rail A.

Both sides of the upper end of the bulkhead are provided with both described means for anchoring, or securing, the bulkhead against the freight.

It will be appreciated that if desired the lower rail member A may be provided with bolts, such as 36, for securing the ends of the lower rails of the frame to the sides of a car.

In Fig. 3, I have shown a bulkhead in relation to a portion of a freight car in dot and dash lines, the vertical lines X designating the sides of the door jamb While the lines Z designate the edges of the floor in the doorway.

Assuming that one end of the car has, been loaded with freight up to a point slightly back from the edge of the door to provide sumcient space for the plates 40 on the bolts 36, the bulkhead is positioned on the floor and the lower ends of the frame members B, are engaged by the chocks 24, and the bulkhead is moved back against the freight by moving the chocks over the floor of the car, and when positioned the chocks are spiked to the floor, or, if the chocks are omitted, the plates 26 may be spiked to the floor. Pressure is then applied to the upper frame member or rail A, to force the portions of the bulkhead between the lower and upper rails A, A, against the freight, and while held in such position, the bolts 36 in both ends of the upper frame rail A, are driven outwardly by the wedges 42 to force the spurs on the bolts 36 into the side walls of the car, and when driven home the pins 44 are inserted in holes in the wedges just below the rail A, to prevent upward movement of the wedges by vibration of the bulkhead.

If both rails A, A are provided with bolts as shown in Fig. 3, or jacks as shown in Fig. 1, it may not be necessary to secure the supportsto the floor of the car in a great many cases which may be determined by the load to be barricaded.

After the bolts have been locked against the sides of the car, the chains 34 may be secured to the hooks 32 on the plates 28, secured to the sides of the car.

If desired, the bulkhead may be provided-with only the bolts, or only the chains and hooks (for anchoring the upper ends of the bulkhead.

It will be appreciated that the rail A, A, may be formed of channel sections as shown in the drawings, while the vertical supports B, B, may be formed of angle sections, one flange being flared and welded to the outer faces of the rails, so that the channel sections may be'used to form uides for the anchoring bolts.

If desired, all of the frame-forming members of either form of bulkhead may be constructed of angle shapes, one of the flanges of the vertical supports B, B being flared to form seats for the top and bottom rails A, A, and tubular members for the bolts may be formed in the ends of the rails by welding the edges of the flanges of short angle sections to the flanges of the rails at the ends thereof for form shown in Fig, 3.

The structure in Figs. 8 and 9 differs from Figs. 1 and 1A only in the construction of the jack and that the channel sections A, A and B, B of the frame in Fig. 8 are positioned at right angles relative to those in Fig. 1 so that the webs of the rails A, A and supports B, B are in the planes of the straps l2 and I6.

By positioning the rails and supports as shown in Fig. 8, the channel sections resist the strain imposed by the stretching of the straps l2 and 16 during their application thereof to the rails and supports than when positioned as in Fig. ll

By positioning the channel sections of the frame as in Fig. 8, the members need not be braced by struts C, C as in Fig. 1 but can be braced by gusset plates C which materially reduces the weight of the barricade as well as the cost. l

The same reference characters have been applied to similar parts in Figures 8 and 9 as applied to the structures shown in Figures 1 and 1A.

The eyes In to which the straps i4 and it are secured in Fig. 8 are welded to the members A, A and B, B at the junctions of the web and one of the flanges on freight engaging side of the frame, While the gusset plates C are welded to the flanges of a member A and B on the opposite side of the frame at each corner thereof.

Welded to each gusset plate C is a nut I8 for a jack in which the screw 19 is threaded and is I provided with the usual spherically shaped head [9 the head [9 of the bolt is rotatably mounted in a tubular member 23 extending from a plate 23 which is provided with spurs extending from the other side thereof. lhe interior of the tubular member is provided with a spherical socket 9 for the head Is the face of which is closed by a plate 23* which is provided with an opening for the bolt which is of sufficient diameter to permit the plate 23 to rock on the bolt head to seat the plate against the lining of the car if the bolt should not extend exactly radially from the center of the socket.

The plate 23 and the tubular member 23 are preferably formed of a steel casting, the bolt is passed through the opening in plate 23' and is then secured to the end of the tubular member 23, preferably by welding. The headed actuating lever 2| is passed through an opening in the end of the screw 19 instead of through a head formed on a shouldered head on the other end of the bolt.

Such a structure greatly reduces the cost of the jack as well as reduces the weight of the structure.

One of the advantages of my invention results from the provision of an all metal bulkhead in which the main frame-forming members are formed of standard rolled metal sections and which are provided with laterally movable means carried thereby arranged to be spread to increase the width of the bulkhead to engage the sides of a freight carrying. compartment of a carrier such, for example, as a freight car, a freight carrying truck; or vessel; and retain a load by pressure applied by the movable means to jam the bulkhead between the Walls of the compartment.

Another advantage of my invention results from the positioning of a flat face of each frame member on the face of the bulkhead or barricade whereby one face thereof is free of projecting portions which might injure articles in contact therewith when positioned as a barricade.

Another advantage of my invention results from the provision of a barricade having bowed transverse frame members provided with means for jamming the barricade between the Walls of a compartment whereby, when positioned with the concave faces of the transverse frame members against a load, any shock of the load against the barricade will tend to straighten the frame members and increase the pressure against one of said members between the walls of the compartment.

Another advantage of my invention results from the provision of corner braces or struts at the corners of the frame, extending from one main frame member to another main frame member at right angles thereto, the ends of the braces being welded to the main frame members with the broad face of each of the struts in the plane of the broad faces of the main frame members In the claims, the term car has been used to designate all types of freightcarriers or compartments in such carriers.
